SPECIFICATION forming par/t of Letters Patent No. 713,728, datedNovember 18, 1902.

Application led April 29, 1901. Renewed March 20, 1902. Serial No.99,034. (N model-3 To t/Z whom zit may concern,.-

Be it known that I, PETER E. WIBERG, a citizen of the United States, anda resident of Bloomfield, in the county of Essex and State OfNew Jersey,have invented certain new and useful Improvements in Safety-PinMachines, of which the following is a specification.

My invention has reference to safety-pin machines, and relates moreparticularly to ro mechanism for coiling the wire and for making andattaching the coil-guard to the pin during the process of themanufacture of the latter. Heretofore the guard which surrounds the coilat the lower end of the pin has been i5 put on by hand after the pin hasbeen manufactured and clenched in position by means of a foot-press.

My invention contemplates means whereby the guard can be stamped outautomatically zo and put on the pin while the latter is being coiled,all in one continuous operation.

To this end the invention consists in the hereinafter-described means,which may be utilized in connection with the process disclosed in asister application executed by me on the 5th day ofApril, 1901, SerialNo. 57,922.

In order to explain myinvention more readily, I have embodied it in themachine shown in the accompanying drawings, in which the 3o invention isconvenientlyillustrated5 but variations and changes may of course bemade within the scope of the claims.

Similar letters of reference indicate corresponding parts in thedifferent views.

I shall describe a safety-pin machine embodying my invention andafterward point ont the novel features in the claims.

Machines for making safety-pins are usually constructed so as to receivea strand of wire and to cut it into suitable lengths for different sizesof pins, after which the lengths of wire are carried, by means of twohelically-screw-cut rods acting as conveyers, to the means for puttingon the cap at the top, making the coil, &c., the points being put on bya set of files acting on the pins while in transit. My machine may beconstructed to act on pins which have or have not had the cap at the topput on or which have not yet been pointed, such matters being immaterialso far as this invention is concerned; but the machine will preferablybe constructed as shown in the drawings.

-A represents the ends of the helical screws which feed the pinsct',shown in thisinstance as being merely pointed without having anycaps put on, and d10 is a rack for keeping the pins on the screws A andto prevent their being thrown off by the rotation of the said screws. Asthe pins reach the ends of the screws A they drop on the anvil m andhave their upper ends bent by the hammer lm2. The hammer m2 is pivotedin the extension c2 of the framework C and is operated by means of thecam d', mounted on the main shaft D. As the pins drop in position on theanvil m they are also supported by the central movable member o of thespindle B. The spindle B is mounted in the bearings b5, adapted to slidein the groove c of the framework C, and carries four members b', h2, b3,and b4. This spindle partakes of three motions-viz., a rotating motion,a reciprocating or longitudinal motion, and a transverse sliding motionin the bearings b5. Besides, the four members b', b2, b3, and b4 eachhave a separate motion independent of but harmonious with the movementsof the spindle. The rotating motion of the spindle B is imparted bymeans of the pinion h6 being rotated by the rack e, carried by theforked lever E, having the roll c2 coperating with the cam e3 on themain shaft D. The lever E is provided with a bolt e4, which slides inthe slot e5 of the lever c6, pivoted at e7 to the framework andprojecting into the bearings b5, whereby the said bearings carrying thespin- IOO die are given a transverse motion back and forth. As thespindle B rotates it moves forward and backward by reason of thethreaded portion' 197 cooperating with the threaded portion 198 in thebearings b5.

The cam e3 is constructed with a portion elo, which operates on theroller e2 so as to cause no movement of the spindle B while the rollere2 is traveling over the said portion elo. Of course when the roller e2is on the return movement the spindle slides back in the bearings 195and rotates in the opposite direction, so that it is moved back to itsoriginal position with each complete revolution of the cam e3.

Upon the extension c5 of the framework C are pivoted four levers f', f2,f3, andj'4, each provided With a friction-rollf5 at one end` engaging,respectively, with the cams f6, f7, f8, andfi, conveniently mounted onthe shaft D. These levers and cams operate the four members of thespindle B, causing the said members to protrude from the latter at theproper time to perform their various functions. The central member Z9'is in the form of a stem extending through the center of the spindle Band terminating in a rounded portion b9, eX- tendinginto the slot]C10 ofthe leverfl, in which slot the said rounded portion is free to movetransversely, so as to conform itself to thetransversemovementofthespindleB. Theleverf terminates in a forkedportion, forming a guidewayf, in which guideway the sq'uare piecef12slides. The square piece]C12 surrounds the spindle B and by itscooperation -With the'guidef11 compensates for the sliding movement ofthe said spindle. The member b3 consists of a pivoted portion Z912,terminating at one end intwo arms Z920 and at the other end in theportion Z913, attached to the stem Z914, provided with a button Z911,extending into the circular groove fle in the square piecef12,whichlatter having a longitudinal sliding movement on the spindle B whenactuated by the cam and lever causes the longitudinal movement of thestem Z914. The circular groove f13 is provided in order that the buttonmay slide in same, and thus adapt itself to the rotation ofthe spindleB.

The coiling member b2 is in the form of a stem and extendslongitudinally through the slot blo and is operated in a manner similarto that described in connection with the member b3.

The guiding member 194 consists of a guide portion Z915 and a stem Z916,operated in the same manner as the members b3 and b2.

The coil-guard G is made from a strip of metal fed in any well-known orsuitable manner to the portion Iq,where it is acted upon by theblanking-die g2, operated by the lever g3, cooperating with the cam g4,after which the blank is operated upon by the forming-die g5, operatedby the levers g6 and g7 and the cam g8.

The guard Gr, after it has been formed, is received by the conveyer H,constructed,

preferably, with two arms h', of springy maA terial, meeting at the topand forming the recess h2, a supporting portion for the guard beingformed by the projection h3 on one of the arms h. The conveyer H has apin 71.25, traveling in the curved slot h4 of the framework and isfurther pivoted at h5 to the arm h6, which latter has a pin-and-slotconnection 71.7 with the lever hs, pivoted at h9 in the framework C andattached at its other end k12 to thev operating-lever 79.10, cooperatingwith the cam hu on the shaft D. The curved slot h4 is so constructed asto bring the conveyer H alternately in alinement with the die mechanismand the point of the pin, as shown in Fig. 2. The lever hf is alsoprovided with a contacting portion hw, havinga sharp edge adapted toengage with a similar contacting portion 7L on the rock-arm h, pivotedat 7x16 and having a pin h at its upper end working in the slot 7tlg ofthe tongs 7tlg, pivoted at h2o to the framework and provided with theljaws b21, adapted to grasp the pin for the purpose hereinafterexplained.

I is a punch mounted on the rock-arm t", pivoted in the framework andoperated by the roller 712, cooperating with thecam t3.

The operation is as follows: The pin, being delivered by the helicalscrews A, is dropped upon the anvil m, where it is operated upon by thehammer m2, thereby both bending and holding the pin; but if the head orcap has already been put on, as shown in Figs. 4f, 5, 6, and 7, meansare provided for grasping and holdingthepinonlywithoutbendingthe same.At this moment the member Z9 will protrude from the spindle B andsupport the pin atthe pointwhereitis to be coiled. The coilingmember 192now protrudes, and the spindle B commencestorotate,thuscoilingthepin.Simultaneously with this the spindle also moves transversely, so as tocompensate for the taking in of the wire as it is coiled, and movesforward a distance equal to the thickness of the material-that is, thewire forming the pin-so as .to enable the strand to be properly coiled.Vhen the wire has been partially coiled, as shown in Fig. 2, the Variousmovements of the spindle cease and it remains in the place indicated,owing to the construction of the cam elo, as hereinbefore explained. Atthis moment the point of the pin is grasped by the tongs h1, so as toinsure perfect alinement, while the conveyer H brings the guard G,previously taken from the dies, and slides it up on the pin, the saidguard being provided with a hole for that purpose. When the said guardhas been brought up a proper distance, the member 193 protrudes from thespindle B and with its two arms Z920 lifts the guard from the conveyerH, the said conveyer returning quickly, and the spindle B again rotatesand moves transversely, thereby continuing the coiling operation untilit is iinished, the two arms Z920 of the member b3 meanwhile pressingthe guard on the coil until it has reached its proper position. Justprior IOO IIO

to this the central member b and the ceiling member b2 are drawn in, theguiding member b4 having just previous to this come out, thus steadyingthe pin. The central member b noW shoots out again, While the punch I,being new opposite te the central member en account et the transversemovement of the spindle, is operated'at the same moment7 thus clenchingthe guard in position on the pin. All the members are new drawn in andthe pin drops into a suitable receptacle on the machine, after which thespindle B returns toits original position and the operation is repeated.

In addition te ceiling the pin and putting on the guard the means hereindescribed Will close the pin, as shown in Fig. 7, if the said pin hasbeen provided with a cap prior tothe operation described herein takingplace.

It Will of course be understood that any suitable form of die may beused. The dies shown in the drawings are merely conventionalrepresentations, and, further, that the guards might be stamped outindependently of the conveying' means and fed to the pins or te theconveying means in some other suitable manner.
